BHA stands for beta hydroxy acid — it's an oil-soluble exfoliant that works inside pores to clear out buildup. This liquid uses 4% Betaine Salicylate, a gentler form of BHA that dissolves sebum and dead skin cells without being too harsh. The lightweight, water-like texture absorbs quickly and fits right into your toner step after cleansing.
Who is This For?
Suitable for all skin types, but especially helpful if you're dealing with blackheads, clogged pores, or excess oil. It's also a great option if traditional salicylic acid feels too intense for your skin.

FAQs
Q: What is the difference between Betaine Salicylate and Salicylic Acid?
A: Betaine Salicylate is a gentler derivative of salicylic acid, making it less irritating while still providing exfoliating and pore-clearing properties.
Q: Can I use COSRX BHA Blackhead Power Liquid every day?
A: It is recommended to start with once weekly use and gradually increase to 2-3 times per week based on skin tolerance; daily use is not advised for most skin types.
Q: Should I use this product in the morning or at night?
A: PM use is preferred; if applied in the morning, sunscreen with SPF 30 or higher is required as BHA can increase sun sensitivity.
Q: Can I use this with retinol or vitamin C?
A: Avoid using BHA in the same routine as AHAs, retinoids, or vitamin C to prevent irritation; alternate them on different days instead.
Q: How long until I see results?
A: Most users notice smoother texture and fewer blackheads within 4-6 weeks of consistent use, though individual results vary.
Q: Is this safe for sensitive skin?
A: The Betaine Salicylate formula is gentler than traditional salicylic acid, but sensitive skin types should patch test first and start with once-weekly use.
Q: Where does this go in my skincare routine?
A: Apply after cleansing as your toner step, patting a thin layer onto dry skin before the rest of your routine.
How to Use
Cleanse your face thoroughly and pat dry. Soak a cotton pad with the liquid and gently swipe across the face, avoiding the eye area. Alternatively, dispense 1-2 pumps into palms and pat evenly onto skin. Allow the product to absorb before proceeding with the next step in your routine. Start by using once per week, gradually increasing to 2-3 times per week as skin tolerance builds. Apply SPF 30 or higher during daytime when using this product.
Used this for about 3 weeks. Love it! Helps with the blackheads on my nose and my pores look smaller. It is good value for what it does. Comes in a strong bottle with a pump dispenser. Would recommend for people with blackhead and big pore problems. Would buy again.

Gentle + It Really Works!
I have combination skin, my skin is dry after cleansing in the AM and gets oily throughout the day. Recently, I've been battling large pore on my cheeks that have been getting congested and clogged easily. The cheek pimples were frequent, they were deep swelling into little mounds, they hurt and were ugly. After cleansing, I applied the toner with my hands by quickly rubbing all over the face and when I did this step... a ton of blackheads from my cheeks would come out sticking onto my palms. It was very gross and I needed some serious help with the blackheads:( I finally decided to try Cosrx Blackhead to use after my toner. It was very gentle and caused no irritation. I used this product everyday and didn't think it was working, but I continued to use it since I already paid $$ for it. After using 3/4 of the bottle, I can attest that the mass of blackheads that would stick to my palms lessened by 90%, no lie. I am now a firm believer that this product works, and I haven't stopped using it since. I highly recommend this product, use it diligently, be patient and see the miracle it can do for you.

one good exfoliator that i use beside AHA7. I have no problem with blackhead, but this product works well on clearing up my pores, controling my sebum, and reducing whitheads on my nose. As my dead skin cells lifted, my skin texture is improving. I have yet to see the effect for my clogged pores tho. I use strong exfo only twice a week, alternately between BHA and AHA7. I'd just pump the liquid to cotton pad, lightly swipe it over my skin, and let it rest for several minutes before my next skincare step

Good product
I like the viscosity, you don't have to use much. Still waiting to see visible effects though only been using it for a week.
